As I understand them an ACR is either connected or not. Think a simple relay, on or off. An electrical circuit 'senses' voltage and at a certain voltage point connects both sides together.
I believe it's 13.4 + or - volts or so. If it senses voltage over the set point it kicks.
I'd think a variable DC power supply and a continuity tester would work. Increase the voltage until the relay connects. Or not. Have to know the voltage it is supposed to connect at too.
